Please take a look at this log and let me know what you think about the idle. I have a slight 200 or less rpm surge but its annoying enough that I want it gone. Let me know if this is normal or if I should adjust something.

I cant log TPS for some reason. I have a 1g TB but have a 2g TPS. Im not sure what settings I should have on link for the TPS so if you can advise there as well I would appreciate it.

The MAF Raw is reading a lot more than the 32Hz that I was informed it should be at.

Problem somewhat solved. Idle switch wasnt working. Simulated idle switch and did a TPS adjustment. -21 offset and 109 scale. I need to adjust my MAFcomp a bit more to get the right airflow per rev and tune for CombFT.

Is it still surging? Try unplugging your TPS and see if it still surges.

Enable your TPS adjustments, then during a log go 100% throttle then stop the log. Right click on the graph, then adjust the TPS. Log TPS voltage if you can. It should show .63v off the throttle, and 5.00v WOT.
